I've had RA for 34 years and am seriously crippled. But I've been able to live alone since my husband died 11 years ago thanks to my 4 dogs. I can't spend all day in bed. I have to get up and tend to them. They entertain me, therefore taking my mind off the pain. When I do cry they're there to comfort me. If a dog is too much for you a cat can be a great companion. I don't know how anyone can live without a pet. God's special gifts.
